[Knob Creek 2016] Bullpup .50 BMG Leader A1

The St. George Arms Leader A1 .50 BMG rifle is the creation of Charles St. George, based off of his previous design, the Leader 50 rifle. It is a semi-automatic .50 BMG magazine fed bullpup rifle with a 24 inch barrel that uses a short stroke gas piston system. The bolt is made out of Maraging steel, which the company claims is an extremely strong material to be used within small arms design (indeed, simple stock prices of the steel are very costly). Magazine is a 10 round Serbu magazine, pistol grip and selector switch are both AR compatible and thus can be switched out. The top rail is a picatinny rail that extends over the extrusion that is the receiver of the rifle. Non reciprocating charging handle is on the left side of the rifle above the pistol grip. There is a picatinny rail underneath the charging handle that bipods can be mounted on, in addition to a picatinny rail behind the magazine for a monopod. The compensator is massive, held together by what appears to be hex screws. The rifle is in full production form and the company is currently taking in orders. It comes in at an overall length of 39.5 inches and an unloaded weight of 18.5 lb.

The current A1 model differs from the original Leader 50 mostly in manufacturing methods rather than an actual design change. The original Leader 50 didn’t come to market, thus this will be the first time it will be available for consumers. The rifle can be made in a left hand version as ordered. The Leader 50 A1 was presented the Blue Book of Gun Value Award for the best original Bullpup design at this years NRA Show.

Charles St. George has an interesting tale that actually begins with the beginnings of the Barrett company. Essentially St. George appears to have came out with the triangular bolt used in the Barrett design before Ronnie Barrett began the company. Forgotten Weapons has an interview with him over this fact where they discuss the design differences. St. George received a patent in 1982 (filed in 1979) for his T2 5.56x45mm rifle that featured a triangular bolt (U.S. Patent Number 4,358,986), while Ronnie Barrett didn’t receive his first patent until October 1989, having been filed in 1987(U.S. Patent Number 4,867,040), for the M82 with a triangular bolt. St. George also did substantial work on the Bushmaster bullpup M17S, so he isn’t a newcomer when it comes to the bullpup design game.

    No sights?

    • Anonymoose

      He said “firing,” not “aiming.” 😛

    • GD Ajax

      For this thing, sights would be worthless. The top rail should mount just about any scope you want though.

      • Porty1119

        Why would irons be worthless?

        • alex waits

          Because man, at the range irons would be useful, the 50 BMG isn’t even up to speed yet! Do you even internet?

          • andrey kireev

            You see Ivan, if your car has mechanical problems, you drive fast, so problems never catch up.

          • Rooftop Voter

            Reminds me of some of the so-called mechanics that would free-rev an engine in the hopes that it would blow the mechanical problem out of the exhaust. Yeah, that will fix that worn timing chain for sure.

        • GD Ajax

          What kind of scrub uses irons on a sniper rifle?

          • Anonymoose

            Certainly not Kirsten Joy Weiss!

  • GD Ajax

    It’ll be a good day when the Leader 50 is no longer a vaporware rifle.

  • jamezb

    Perfect for CQB vs. ROBOTS!!!

    • Ryfyle

      Or horrible Mutants. Robots can be subverted through shear trolling and freak porn.

    Finally something to deal with my huge Pigman problem.

      ManBearPig is a real threat! I’m super cereal!

      Stay away from Pink Floyd laser light shows, bro.

  • zaqzilla

    The only practical reason I can think of for this is It would be easier to carry to the top of a building via the stairs then the other .50 cal rifles.

    • kyphe

      The only practical reason I can think of is when firing in confined spaces if the aim is not to have the barrel protrude out of concealment.

      • iksnilol

        Do y’all not realize how awkardly long conventional config .50 BMGs are? This brings the .50 BMG to a more “normal” length.

        • SP mclaughlin

          Hey, if Price and MacMillan could carry an M82 undetected through Chernobyl…..

      • El Duderino

        CQB .50 cal…that’s funny right thar.

  • Bierstadt54

    When Jurassic Park 4 lets the T-Rexs escape into my town, this will be my EDC piece.

  • GD Ajax

    Doesn’t count scopes in WW2 were crap.

  • Havok

    Well the fact that he worked on the Bushmaster M17S answered all of my questions.

    • Machinegunnertim

      Just because Bushmaster made it cheaply and let the design stagnate doesn’t mean anything against C. St. George, his design was good. Look what they did to the Magpul Masada (ACR) for goodness sake.

      • Havok

        Didn’t mean it as in “crappy product”. Meant it more referring to the aesthetics.

        • Machinegunnertim

          I agree, though they are easily remedied by milling holes and slots in the receiver and placing a single rail across the top. People have been doing it for years, but Bushmaster couldn’t?!!? What the hell is wrong with them?

  • DanGoodShot

    Looks like it mitigates recoil fairly well. I wounder why they built the brake the way they did? Good for cleaning though. I find that to be the hardest part to clean on my rifles. It drives my OCD nuts! Lol

  • SP mclaughlin

    Please make a 12 gauge version of this with a drum mag, St. George.

  • Risky

    I hope there are some well engineered places for gas to go in case of a failure in the chamber. I think that a .50 caliber kaboom or out of battery detonation could very well kill you with your face that close to the chamber.
